1. Drain the spent bleaching liquor2. Fill with fresh cold water to obtain a liquor ratio suitable for
dyeing3. Check that pH is in the range 5-10 (6-7 is most suitable) and
temp 20-60 centi.4. Add 0.1-0.2g/l diluted catalase liquid and start circulation5. Check after 10-20 min6. Continue with dyeing in the same bath

Product Description:

Catalase Liquid is a kind of enzyme preparation fermented by
Aspergillus Niger; it can effectively catalyze / decompose hydrogen
peroxide into oxygen and water.

It only reacts with hydrogen peroxide.

low energy and water consumption requirements are increasingly used
in pre-treatment processes for bleach clean up before dyeing

Product Advantages:

Water saving: only one cold rinsing is required

Time saving: reduce rinsing time, the bleach clean up only need
10-20 min

Energy saving: shorten processing time and no heating

Safety: hydrogen peroxide can be completely broke down before
dyeing

Notes:1. When the density of H2O2 is higher than 1000 PPM, the enzyme CANNOT work well.2. The activity of enzyme will be the best at 50℃, but it is NOT
recommended to dye directly if treated at 50℃.3. After treated for 10~20min, you can use the MDRCK test paper to
test the density of residual H2O2.
